CI 3 form helper add new lines after form_element

Hi there,
In CI 2, the following code

PHP Code:

echo "before" . form_input("test") . "after"; 


Used to return :

Code:

before<input type="text" name="test" />after

In CI 3, it returns :

Code:

before<input type="text" name="test" />
after

It may be a feature, but it's a bug to me, as I use it in javascript string, and javascript doesn't like new line in the middle of a string.

Thanks
